I thank all the people who have sent me solutions to my Conj problem. Unfortunately, none of them seem to work.
The issue is adding a value to a defined vector - (def savedColors [black, white]) One solution was given as: (swap! savedColors conj newcolor) This produces still the following runtime error: Exception in thread "AWT-EventQueue-0" java.lang.ClassCastException: clojure.lang.PersistentVector cannot be cast to clojure.lang.Atom Another solution was to make savedColors an atom - (def savedColors (atom [black, white])) This produces a new compile error: Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: Don't know how to create ISeq from: clojure.lang.Atom Changing savedColors to a list instead of a vector gets the same error. The atom example on the web is for a map. I'm sure this can be done. So far I just don't know how. Bill -- You received this message because you are subscribed to the Google Groups "Clojure" group.
